' OIL-DISPENSINGDEVICE.

Application filed. Cotober 7, 1924.

To all whom it may concern:

Be it known that .l, Hnnnnn'r B. TIMMS, a citizen of the Unit-ed States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Oil-Dispensing Devices, of which the following is a specification.

This invention primarily relates to oiling devices, but it more especially comprehends the type adaptable for the oiling of watches and similar delicate machinery.

An important object of this invention is to provide a device of this character formed entirely of metal and properly designed to deliver the required amount of oil to watch jewels and the like.

A further important object of this invention is to provide an oiling device of this character formed with an oil containing eye and so constructed that pressure on the device will only deliver or dispense a certain quantity of oil to the jewel or other parts to be oiled.

Vl ith these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of reference indicate like parts throughout the several figures, of which:

Figure 1 is a perspective view of my improved oil dispensing device; and

Figure- 2 is a view partly in section and partly in elevation of Fig. 1.

I, of course, am aware of many types of oiling devices for dispensing oil to working parts of various mechanisms, but for the most part they present either compressible oil containing reservoirs or hollow tube outlets or both, which are not adaptable to di pense oil to delicate mechanisms such as watches, being incapable of properly reaching the parts and also calculated to dispense too much oil, which in connection with delicate mechanisms is more or less disastrous, and it was to overcome such deficiencies, and to provide a neat compact device constructed entirely of metal and which would, even under a normal degree of pressure dispense a certain quantity of oil and no more, so as not to flood the parts being lubricated as well as other parts, where the mechanism is of delicate construction,

Serial No. 742,216.

that I designed the improved oiling device for watches and the like, forming the subject matter of this invention.

In the illustrated embodiment characterizing this invention there is shown an oiling device A comprising a stem 5 bifurcated at point substantially spaced from its lower end as at 6 to provide a pair of elongated prong members 7 tapering in thickness from their upper to their lower extremities and directed inwardly or towards each other so as to snugly contact at their lower ends and form in ei'l'ect a single point exteriorly rounded as at 8.

The said prongs 7 are spaced at their upper ends as at 6 and taper gradually inwardly until they contact at their lower ends as at 8 to form a substantially wedge-shaped eye or oil containing space 9, and each of their inner sides are preferably formed with a longitudinally extending groove 10 which not only tends to hold the oil in the said eye 9 but also to direct it to the point 8 and to the jewel or other part to be oiled.

While in most cases contact with the part to be oiled will deliver a suliicient quanity of oil, a slight pressure on knob 11 will very slightly deflect outwardly the prongs 7 intermediate their length which action will dispense a certain additional amount, but not sufiicient to flood the parts being oiled. It will thus be seen that it is essentially importantthat the prongs 7 be of the proper temper or elastic spring quality, else when pressure is exerted on knob 11, either no oil or too much will be delivered to the parts.

From the above it will be apparent that I have evolved an oiling instrument for delicate mechanisms of unique design, neat in appearance, simple in construction, manufacturable at a negligible cost, and proficient for the purposes intended.

Although in practice I have found that the form of my invention illustrated in the accompanying drawings and referred to in the above description as the preferred embodiment is the most eflicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize that various minor changes in details of construction, proportion and arrangement of parts, may be resorted to within the scope of the appended claim without departing from or sacrificing any of the principles of this invention.

H aving thus described my invention, what t aining eye or space, the inner sides of said I desire protected by Letters Patent is as set prongs being grooved.
